...library system was a collection of dark buildings filled with shabby books and headed by inept political appointees. Reform groups demanded that something be done. The first trained librarian they picked died in office after only a few months. The second time they were luckier: they got a bookish, pipe-smoking Tennessean named John Hall Jacobs...
...During dredging operations in the Delaware River, Army divers found the wreck of an English vessel sunk in 1750. Unable to raise the ship, the Army pumped most of its cargo through a suction pipe, spewing a mass of silt and 18th Century pewter plates, brass buttons, locks & keys, and silver shoe buckles on the riverbank...
...cutting a narrow trench 80 feet from the mill, Godfrey hopes to find traces of the "ambulatory walk" of the Norse church. Uncovered thus far: a 1696 King William III penny, a lead musket ball, an old brass button, a clay pipe...
...planes are pushed by the reaction of the blast of hot gas shooting out the tail pipe. The present problem is that this blast is speeding much too fast-at about 1,300 m.p.h. Even when the plane is flying at 600 m.p.h., the blast is shooting backward in still air at 700 (1,300 minus 600) m.p.h. The engine is still wasting too much energy merely stirring up the air. To approach the normal propulsive efficiency of a propeller plane, a jet plane would have to fly faster than sound. But one arresting compensation-for the jets-is that...
...Only when the engine is set up with a pipe to catch its gases is it safe to watch the fires kindle. *The power of jet engines is measured in pounds of thrust. The propulsive horsepower developed varies with the speed. At 375 m.p.h., one pound of thrust equals one "thrust horsepower." * Spruce, tweedy Whittle, 41, comes nearest to being the inventor of the turbojet. Recently the British Labor government, with a grand Old Regime gesture, handed him a tax-free thank you of ?100,000. *Pronounced mack. Named after Austrian Physicist Ernst Mach...
